R works with objects that consist of elements. The smallest elements are numbers and characters.
R Archive Network (CRAN) and is aimed at R users, must be accompanied by a help file.anova(), then you just type ?anova or help(anova) in the console.If you do not know the name of the function: type ?? followed by your search criterion. For example ??anova returns a list of all help pages that contain the word ‘anova’
Alternatively, the internet will tell you almost everything you’d like to know (and then some)
Google can be of tremendous help.
R related issues; use ‘R:’ as a prefix in your search termAssigning things in R is very straightforward:
<-For example, if you assign the value 100 (an element) to object a, you would type
a <- 100
<- in an R fileCalling things in R is also very straightforward:
For example, we assigned the value 100 to object a. To call object a, we would type
a
## [1] 100
This is why we use R-Studio.
